PHP分頁範圍

Question

我有一個分頁腳本，它工作正常。我想爲我的分頁添加一個範圍。它應該採用以下格式;

< < < 1 | 2 | 3 | 4 | 5> >>

當我點擊「5」時，它應該是;

< < < 4 | 5 | 6 | 7 | 8> >>

同樣當點擊「8」時，它應該是;

< < < 7 | 8 | 9 | 10 | 11> >>

假設「11」是最後一頁，如果我們點擊11，它應該是;

< < < 7 | 8 | 9 | 10 | 11> >>

我的代碼是這樣的;

$recordLimit = 4; 

    $totalNumberofRecords = 100; 

    $currentpage = !empty($startPage) ? (int) $startPage : 1 ; 

    $startFrom = ($currentpage -1) * $recordLimit; 

    $limit = $startFrom.','.$recordLimit; 

    $totalPages = ceil($totalNumberOfRecords/$recordLimit); 

    $j = 0; 

    for ($i = max(1, $currentpage - 1); $i<= min($currentpage + 4, $totalPages); $i++) { 

$fairLists['pages'][$j] = $i; 

if ($startPage == $fairLists['pages'][$j] || ($j == 0 && empty($startPage)) 
    { 
    $fairLists['pages'][$j] = array($i ,"font-weight:bold;"); 
}else{ 
    $fairLists['pages'][$j] = array($i , 'font-weight:normal;'); 
} 
$j++; 

}

我想的範圍限制爲5，而當我們到達的範圍內，它應該顯示1個此前的紀錄和3條一個記錄;

如果有人知道的腳本，然後請大家幫幫我，

感謝，

阿倫

您的問題由我解決了..我的代碼，但在使用此代碼，如果它後爲你工作，那麼請打這個意見作爲一個答案..... 代碼是

<php 
$page = isset($_GET['page']) ? $_GET['page'] : 1; 
$recordsPerPage = 10; 
$fromRecordNum = ($recordsPerPage * $page) - $recordsPerPage; 

$query = "SELECT * FROM 
     table_mstr_department 
     ORDER BY DeptId 
     LIMIT 
     {$fromRecordNum}, {$recordsPerPage}"; 


    $stmt = $con->prepare($query); 
    $stmt->execute(); 
    $num = $stmt->rowCount(); 


    echo "<div id='search_area'>"; 
     echo "<table width='100%' border='0' cellspacing='0' cellpadding='0'>"; 
       echo "<tr>"; 
        echo "<td colspan='3'></td>"; 
       echo "</tr>"; 

       echo "<tr>"; 
       //********Add New Department Button 
        echo "<td height='auto' width='auto'>"; 
         echo "<input type='submit' name='newemp' value='Add New Department'>"; 
        echo "</td>"; 
        echo "<td width='auto'></td>"; 

        //******Search Button 
        echo "<td width='auto'>"; 
          echo "<div id='search_options'>"; 
            echo "<input type='search' name='search_text' width='auto' style='height:20px;'/>"; 
            echo "<input type='button' name='search_btn' value='Search' />"; 
          echo "</div>";

        echo "<td width='auto'>";

     echo "</tr>"; 

    echo "</table>"; 
    echo "</div>"; 

if($num>0)

    echo '<th>Department Id</th>'; 
    echo '<th>Department Name</th>'; 
    echo '</tr>'; 
    $i=0; 


    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) 
    { 
     $i++; 
     if($i % 2 == 0) 
     { 
      $bgcolor= "#6AA2C3"; 
     } 
     else 
     { 
     $bgcolor= "#A2B5CD"; 
     } 
     //extract row, this will make $row['firstname'] to just $firstname only 
     extract($row); 

     //creating new table row per record 
     echo "<tr bgcolor='$bgcolor' id='$DeptId' name='edit_tr'>"; 
    echo '<td id="edit"><input id="edit" type="radio" name="deptid" value="DeptId" ?></td>'; 

    echo "<td class='format'>{$row['DeptId']}</td>"; 
    echo "<td class='format'>{$row['DeptName']}</td>"; 
    echo "</tr>"; 
    } 


    echo "</table>"; 
}

      else

      } 
     } 
    }

     // ********** show the next page 
     $next_page = $page + 1; 
     echo "<a href='" . $_SERVER['PHP_SELF'] . "?page={$next_page}' title='Next page is {$next_page}.' class='customBtn'>"; 
      echo "<span style='margin:0 .5em;'> > </span>";

     // ********** show the last page 
     echo "<a href='" . $_SERVER['PHP_SELF'] . "?page={$total_pages}' title='Last page is {$total_pages}.' class='customBtn'>";

    } 

    /* 
    echo "<input type='text' name='page' size='1' />"; 
    echo "<input type='submit' name='Go_btn' value='Go' class='customBtn' />";<?php */ 

echo "</div>"; 
?> 

您可以相應地修改這些代碼。此代碼顯示三列... 祝您好運.....，不要忘了喜歡這個作爲asnwer
